Exhaust Shootout: Which is Best on the Yamaha YZ450F?

[@yz-pc9xi]

Thank u! For $1300 I think I'll also stick with the stock pipe.

[@Sleepy.Time.]

stainless steel pipe would cost half that or less with the same performance of the Ti/carbon

[@yz-pc9xi]

@Sleepy.Time. a ss system is still over $1000. A slip on is almost $600. The juice ain't worth the squeeze.

[@Sleepy.Time.]

@@yz-pc9xi i agree that is to much

[@christerstefansson3249]

Its all bling nowadays , On the YZF u fix the power delivery with an ap in your phone. Acrapovic is 1,700 dollars. One tipover on the right side and its all scratched up.

[@nickwukmir9853]

Just for weight reduction witch is much needed.

[@stephenmiley5804]

Thanks for taking the time to do this exhaust shootout, feels like it's been a very long time since I've seen an exhaust shootout on any bike!

[@UnsungThermidor]

Would have loved to see the Bills RE-13 and Akrapovic Evolution in this shootout. Another neat shootout idea would be a slip on comparison for those who wanna buy something but not eat the full system price. Cant wait for my hydraulic clutch though, its always sold out.

[@holeshot48r1]

Rocket exhaust would be another one to add to their list. They're easy on your wallet. They sound good, and they have reasonable gains in the power department...

[@jpesicka492]

If I’m buying one it’s a Bill’s Pipe.

[@UnsungThermidor]

@holeshot48r1 if Im not mistaken I dont think Rocket makes a pipe for this year YZ

[@michaelratanakul4964]

Awesome comparison! just too bad the Akrapovic exhaust wasn't there 😁

[@fox13z400]

Agreed, but for what it cost most of us wouldn't be able to afford it anyway. Better to just get an ECU and keep the stock exhaust.

[@dirtripper77]

i love my akrapovic over the stock

@@fox13z400 ecu cost nearly as much as the Akrapovic lol

[@andrewbecker3700]

Could've bought anything, but went with the Pro Curcuit T6 complete exhaust on my '21. I wanted durability with a U.S.F.S. approved spark arrestor. With the maps I have loaded in the ECU, and the induction mods I've made. I went up a tooth on the front and 2 on the rear when I upgraded the chain and sprockets. 3.73 ratio up to 3.64. Pulls so hard through every gear it's way more manageable, yet linear. The exhaust was probably the biggest factor in getting the completely insane amounts of power this thing is making. The stock exhaust was way to squirty. Unmanageable. Now it's got the broadest powerband of any dirtbike I've ever riden. It just pulls so damn hard in every gear, it's scary. I'd estimate top speed is gotta be near 100mph with those gears. If your not on a track worried about a few lbs. and you want a durable exhaust system. It's my belief the Pro Curcuit T6 stainless complete exhaust is the only way to go. I paid $799 for it in '21.

I wonder how bills would have stacked up.. good work I love pipe shoot outs.

[@stevesmith756]

I love how light the Ti FMF is but you can’t buff out scratches on the blued muffler

[@OGLD]

Sure can’t. Mine looks terrible from laying it over on the exhaust side a few times

[@JoshStreetDesign]

I absolutely love how loud my FMF is on my SXF 450, but man if you just crash one time that pipe looks like it's old, it scratches so easily

@@JoshStreetDesign strange on my SXF450 my FMF is almost as quiet as the stock muffler which is ok just don’t scratch it

@@stevesmith756 did you take the spark arrestor out? Mine is a 22 with the stock header. Dude I swear it is the loudest bike I've ever ridden and I've ridden a lot of bikes.

[@mikebrown41182]

Great segment Mosiman. Would love too see Acrapovic thrown in there with their main blue program is actually the yzf 450 factory MXGP, but i am also suprised by FMF, given how much R&D they do with factory Yamaha and Eli´s and Coops application, one thought they would implement some of it? Thus ofc their powerbands are different than stock, but a bit more punch. But tbh, how many variables are there to make the bike meatier, exhaust is one good bolt on change. Now this entire test with two stroke aswell would be pretty cool, plenty to choose from there aswell, Mitch have some previously secret sauce with his pipes and silencer combos few knows about.

[@karlslidingdoorguru1785]

The Best Times in my last 50 years included FMF. Don Emler brings more joy to families than Santa Clause

[@leonardooo01121]

Test without Akrapovic ?

[@thisismenotgivingafu]

Right? What’s even the point?

[@rgoeman9368]

These guys probably only use stuff that's given to them. Notice alot of KTM bias? Akrapovic said "who are you?" Yeah you can buy it, but they're moto guys so they are cheap.

[@jpesicka492]

Keefer runs an Akrapovic on his but said FMF was great too. He chose Akrapovic because he said it smoothed out the power and didn’t need to be repacked as soon as the FMF.

[@jhheintz450]

Great test. Considering this bike and would prob go with a Vortex from XPR or Twisted. If I couldn’t use some of the great GYT maps that are out there

[@randytidwell5836]

now you need to do a pipe shootout on the Honda crf250r. how long has it been since the Honda got some love?

[@KingofKhakis]

So which one would make the most power on a Stark Varg? Asking for a friend.

[@murraywiles]

Fmf

[@dylanp9211]

Pro circuit for life 🔥 the blue fmfs look pretty good tho. Feel like pro circuit performs best though. Akrapovich are pricey wouldn't mind seeing how they perform. Yoshi is always solid but again rather have a pro circuit. Dr d looks good tho too. That hgs header looks awesome too and nice smaller muffler. Titanium pro circuit for me. For Atv Motocross i like the Motoworks, Empire's, TC, & Rp Race exhaust. Side note that drd sounded good to me nice and loud baby. And raspy sounds good to me just like the 250f's all raspy and high revving sound amazing.

Ive always Prefered pro circuit for the looks and performance but i like to cut mine down by 1/1-2in gives a sound that i prefer more and lose some weight as well as gaining looks theyre just sooo long

[@AndrewDupin]

Were they all run with a stick tune?

[@wroomfn2414]

1) its a shame not to have akrapovic pipe on this list 2) i guess it is too easy for mxa to dyno the bike with different pipes to get the real picture of how each pipe changes the tourqe and hp so they decided to make a video with two guys telling five times “ohhh it increases hp and smoothens the powerband” (obvious shit) idea of the video: 12/10 realisation: 0/10

Did any of the pipes come with new fuel/ignition maps? Did any of the pipes benefit from a tune? Which pipes were quieter than stock? Noisier than stock? I had an FMF on a YZ250F 15 years ago and it was stupid loud and seemed to add no power.

[@grahamhenry3436]

I have a hgs system in my ktm it’s one of the cheapest you can get them from 900-1400 and it has a nice sound it makes the power smoother but also gain a ton from everywhere it’s better than fmf or pc, yoshi or Akra I don’t know cause I never ran them

Exhaust is the biggest waste of money. 1200-1500 for max 3/4 hp

Exhaust isn't normally all about the HP gains, but how it manipulates the power curve. The problem is the vast majority of people believe it's about the power gains.

[@UnsungThermidor]

Engine mounts can change frame flex characteristics and how bikes track on the ground. However, not all bikes or riders benefit from aftermarket mounts. Some bikes benefit massively from them like the KTM, and the 2023-2024 Yamaha. Even notice riders who are more aware of their bikes feeling and suspension can feel the difference. Will it make you faster? Depends if it gives you more confidence. Or not. But before mounts always make sure your suspension is set up and well maintained.
